Facebook charging $1 fee to send messages to non-friends

San Francisco: Facebook says it is testing a service that will charge users $1 to guarantee that messages they send to people they are not connected to arrive in users' inboxes, rather than in an often-ignored folder called "other."

Launched in 2011, the "other" folder is where Facebook routes messages it deems less relevant. Not quite spam, these include messages from people you most likely don't know, based on Facebook's reading of your social connections. Many users ignore this folder.

"For example, if you want to send a message to someone you heard speak at an event but are not friends with, or if you want to message someone about a job opportunity, you can use this feature to reach their Inbox," Facebook said in an online post. "For the receiver, this test allows them to hear from people who have an important message to send them."
